Description

Technical Field

[0001] This utility model relates to the field of flat cable technology, and in particular to a high-speed signal flat cable. Background Technology

[0002] As electronic devices become smaller, more multifunctional, and faster, higher demands are being placed on the cables connecting these devices. This is especially true for applications requiring the transmission of high-speed differential signals, such as high-speed data communication, computer interconnects, and consumer electronics, where signal integrity and interference immunity become critical factors.

[0003] In existing high-speed signal transmission cables, twisted pairs or other forms of physical isolation are typically used to reduce electromagnetic interference (EMI) and crosstalk in order to ensure signal quality between differential signal pairs. However, in some compactly designed small devices, it is difficult to achieve sufficient physical isolation due to space constraints; in addition, traditional cable structures may cause increased signal attenuation at high frequencies, affecting data transmission performance. Utility Model Content

[0004] This invention aims to at least solve the technical problems existing in the prior art. To this end, this invention proposes a high-speed signal flat cable, which facilitates wiring and saves space, increases the distance between differential signal conductor groups, thereby effectively reducing mutual interference between signals and improving the quality and stability of signal transmission.

[0005] A high-speed signal flat cable according to some embodiments of the present invention includes a ground conductor, differential signal pair conductor groups, an insulating layer, and a shielding layer. The ground conductor and the differential signal pair conductor groups are both disposed within the insulating layer, and the shielding layer is disposed on the outer periphery of the insulating layer. There are two or more differential signal pair conductor groups, and a ground conductor is disposed between each pair of adjacent differential signal pair conductor groups. A connecting plate is disposed at the end of the insulating layer, and the ground conductor and the differential signal pair conductor groups both protrude outward to the connecting plate. Two or more notches are formed on the end of the connecting plate, and the notches are disposed at the ends of the differential signal pair conductor groups.

Furthermore, by optimizing the internal conductor layout—that is, setting a ground conductor between every two adjacent differential signal pair conductors and setting a connecting plate with a notch at the end of the insulation layer—the distance between differential signal pair conductor groups is increased, thereby effectively reducing mutual interference between signals and improving the quality and stability of signal transmission. At the same time, the longer ground conductor ensures the shielding effect, reduces the influence of external electromagnetic interference, and ensures better signal integrity.

[0010] According to some embodiments of the present invention, a high-speed signal flat cable is provided at both ends of the insulation layer, and both ends of the grounding conductor and both ends of the differential signal pair conductor group extend outward to the connecting plate. Two or more notches are provided at both ends of the connecting plate.

[0011] According to some embodiments of the present invention, a high-speed signal flat cable has reinforcing plates provided on the bottom surfaces of both ends of the insulation layer, and the bottom of the connecting plate is connected to the top of the reinforcing plate.

[0023] like Figures 1-2 As shown, this embodiment of the present invention provides a high-speed signal flat cable.

[0024] A high-speed signal flat cable includes a ground conductor 1, differential signal pair conductor groups 2, an insulation layer 3, and a shielding layer 4. The ground conductor 1 and the differential signal pair conductor groups 2 are both disposed within the insulation layer 3, and the shielding layer 4 is disposed on the outer periphery of the insulation layer 3. There are two or more differential signal pair conductor groups 2, and a ground conductor 1 is disposed between each pair of adjacent differential signal pair conductor groups. A connecting plate 5 is disposed at the end of the insulation layer 3. The ground conductor 1 and the differential signal pair conductor groups 2 both protrude outward onto the connecting plate 5. Two or more notches 6 are formed on the end of the connecting plate 5, and the notches 6 are disposed one by one at the end of the differential signal pair conductor groups 2. The length of the ground conductor 1 is greater than the length of the differential signal pair conductor 2.

[0025] This invention retains the advantages of a flat shape, facilitating wiring and saving space. Furthermore, by optimizing the internal conductor layout—specifically, by placing a ground conductor between every two adjacent differential signal pair conductors and providing a notched connecting plate at the end of the insulation layer—the distance between the differential signal pair conductor groups is increased, effectively reducing mutual interference between signals and improving signal transmission quality and stability. Simultaneously, the longer ground conductor ensures effective shielding, reducing the impact of external electromagnetic interference and ensuring better signal integrity.

[0026] In this embodiment, a high-speed signal flat cable is provided, wherein the number of grounding conductors 1 is one more than the number of differential signal pair conductor groups 2, and a differential signal pair conductor group 2 is provided between every two adjacent grounding conductors 1. Specifically, the design of having one more grounding conductor than differential signal pair conductor groups ensures that each differential signal pair is surrounded by a grounding conductor, thereby providing more effective electromagnetic shielding, reducing crosstalk between adjacent signal pairs, and improving signal integrity and noise immunity.

[0027] This embodiment describes a high-speed signal flat cable, including a high-current conductor 7 disposed outside the grounding conductor 1. The high-current conductor 7, the grounding conductor 1, and the differential signal pair conductor group 2 are arranged side by side. Specifically, by adding the high-current conductor 7 and placing it outside the grounding conductor 1, the flat cable can simultaneously support data transmission and power delivery, meeting the requirement of modern electronic devices for power and signal to share the same cable, simplifying the wiring system, and improving integration.

[0028] This embodiment describes a high-speed signal flat cable. Both ends of the insulation layer 3 are provided with connecting plates 5. Both ends of the grounding conductor 1 and the differential signal pair conductor group 2 protrude outwards onto the connecting plates 5. Each end of the connecting plate 5 has two or more notches 6. Specifically, the connecting plates 5 at both ends of the insulation layer 3, and the outward protrusion of the grounding conductor 1 and the differential signal pair conductor group 2 onto the connecting plates 5, facilitate electrical connection with other components and enhance mechanical strength, ensuring the stability and reliability of the cable during use.

[0029] This embodiment describes a high-speed signal flat cable, in which reinforcing plates 8 are provided on the bottom surfaces of both ends of the insulation layer 3, and the bottom of the connecting plate 5 is connected to the top of the reinforcing plates 8. Specifically, providing reinforcing plates 8 on the bottom surfaces of both ends of the insulation layer 3 and connecting them to the bottom of the connecting plate 5 not only increases the overall structural robustness of the cable but also improves its bending performance, making it more durable and suitable for applications requiring frequent movement or flexible wiring.

[0030] This embodiment describes a high-speed signal flat cable. The shielding layer 4 includes an upper shielding layer 9 and a lower shielding layer 10. The upper shielding layer 9 and the lower shielding layer 10 are disposed at the upper and lower ends of the insulating layer 3, respectively. The lower shielding layer 10 is located between two reinforcing plates 8. Specifically, the design of the upper and lower shielding layers, especially the lower shielding layer 10 located between the two reinforcing plates 8, provides more comprehensive electromagnetic shielding protection, effectively isolating external electromagnetic interference, and also helps maintain the purity of internal signals, improving the efficiency and stability of data transmission.

[0031] The high-speed signal flat line described in this embodiment includes a differential signal pair conductor group 2 comprising two transmission conductors 11.

[0032] It is understood that in some embodiments, the width of the grounding conductor 1 is greater than the width of the transmission conductor 11. Specifically, designing the width of the grounding conductor 1 to be larger than the width of the transmission conductor 11 can further increase the spacing of the differential signal pair conductor group 2, while ensuring sufficient grounding area to maintain good electromagnetic compatibility (EMC). The wider grounding conductor 1 can also help dissipate heat, thereby improving the thermal stability of the cable.

[0033] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
